Im on 100mg twice a day. I got mine from matrix nutrition through groupon so got an offer. They seem to be working, 4lb in 5days cant be bad! People think im mad but ill give anything a try especially when people say theyve lost weight on them. Im getting no side affects off them just burped today n tasted raspberries lol. I just want the extra weight ive gained these past couple of years off which is only 2stone so not askin for much even though i probs wont lose that much coz id be 8st xxx
